In order to make technical scheme of the present invention clearer, clear, will combine accompanying drawing to do further to detail below.
Embodiment
Embodiment of the invention solution mainly is to detect spreading parameter in the ring-back tone detection incident of bag such as the call establishment sound through the detection incident in protocol package H.248, can convenient, fast realization to detection, the reporting functions of called subscriber condition.
As shown in Figure 1, one embodiment of the invention proposes a kind of method of NGN network user's status report, comprising:
Step S101, gateway receive the Indication message of this gateway detection called subscriber condition of indication of Softswitch transmission, and Indication message carries H.248 protocol package detection incident;
The gateway that present embodiment method running environment relates to the soft switch (being Softswitch in the present embodiment) of the conduct control network element in the NGN network and connects network element as medium; Detect to the prior art gateway and can't use the H.248 characteristics that report of agreement of standard after the User Status; Present embodiment has been realized a kind of method that reports User Status of closing at NGN network implementation existing network through expanding H.248 agreement.
Gateway belongs to gateway for the called subscriber in the present embodiment; In the present embodiment; In the time of in setting up the voice call calling, need broadcasting ring-back tone to the calling subscriber; Gateway through Softswitch indication called subscriber place detects called subscriber condition, if the called subscriber is in idle condition, then indicates controlled tone playing equipment to broadcast ring-back tone to the calling subscriber through Softswitch or broadcasts the CRBT sound etc. of called subscriber's customization; If the called subscriber has been in talking state, then put suggestion voices such as busy tone or called subscriber busy to the calling subscriber.
In standard agreement H.248, different service uses the different protocol bag to realize, detecting bag with the call establishment sound in the protocol package H.248 in the present embodiment is that example describes.H.248 the protocol definition of standard the call establishment sound detect bag (cd bag), can detect required various signal tones in the call establishments such as busy tone, ring-back tone, stand by tone.
Present embodiment is before broadcasting ring-back tone to the calling subscriber; Softswitch sends Indication message to gateway; And in Indication message, carry the H.248 ring-back tone detection incident of the call establishment sound detection bag of protocol definition, detect called subscriber condition with the indication gateway.
Step S102 detects called subscriber condition according to Indication message;
Step S103; The spreading parameter that detected called subscriber condition is carried in the protocol package detection incident H.248 reports Softswitch through response message, so as Softswitch according to called subscriber condition indicate controlled tone playing equipment for the calling subscriber broadcasts corresponding signal tone.
Among above-mentioned steps S102 and the step S103, the called subscriber belongs to gateway and according to the Indication message that Softswitch sends called subscriber condition is detected, and detected called subscriber condition is reported Softswitch.Called subscriber condition comprises in the present embodiment: non-calling user busy condition, talking state, idle condition and/or error condition etc., wherein, non-calling user busy condition comprises: states such as off hook state, user dialing state, tin ring-back tone and busy tone.
The mode of agreement realizes reporting of called subscriber condition information to present embodiment through expanding H.248; Detecting bag with the call establishment sound is example; Be specially: the use standard H.248 call establishment sound of agreement detects bag (cd bag); Through detecting spreading parameter (cd/rt{substate=x}) in the ring-back tone incident (cd/rt), report Softswitch to the spreading parameter that detected User Status is carried in the ring-back tone detection incident that the sound detection wraps through response message by gateway at cd bag.Wherein, cd is that the H.248 protocol call of standard is set up the process sound and detected bag; Rt is that the signal tone of the call establishment bag of standard detects incident; Substate is the present embodiment spreading parameter, is used to identify called subscriber condition; " x " is parameter value; The User Status that the different parameter values representative is different; For example: can represent talking state, 2 to represent idle condition, 3 to represent error condition etc. with 0 representative non-calling user busy condition, 1; Parameter value includes but not limited to above-named several kinds of state values, and parameter value can increase in order to the more how possible called subscriber condition of sign according to different needs.
When Softswitch receives the called subscriber condition that gateway reports, Softswitch according to the different called User Status indicate controlled tone playing equipment for the calling subscriber broadcasts corresponding signal tone.In the present embodiment, controlled tone playing equipment comprises media server or called subscriber's gateway or other gateways; Wherein, signal tone comprises: CRBT sound, busy tone and/or stand by tone etc.Such as: the called subscriber is an Idle state, then puts the CRBT sound to the calling subscriber; The off-hook attitude is then put busy tone to the user; The voice call attitude is then put " user that you dial is busy, please dials after a while again " or verbal announcements such as " user that you dial converse, and please not want on-hook " to the user.
Present embodiment utilizes the control framework of existing NGN network and characteristics that H.248 protocol package can flexible expansion; Through spreading parameter in the ring-back tone detection incident that detects bag in protocol package H.248 such as the call establishment sound, can convenient, fast realization to the detection and the reporting functions of called subscriber condition; Simultaneously, the method has broad applicability, not only is applicable to Ring Back Tone service, for might need detect the application scenarios of User Status, all can use the method.When the method detects the parameter of bag at extension standards call establishment sound H.248, only need parameter of new expansion, make full use of the characteristics that different parameter values can be represented different User Status, cover all possible User Status.
